COUPLING MECHANISM FOR EMBROIDERING-MACHINES. i

Sp ecication of Letters Patent.

Patented Nov. 3, 1908.

Application filed January 19, 1907. Serial No. 353,034.

To all whom it. may concer-n:

Be it known that I, JOSEPH A. GaonBLr, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful 1mrovements in Couplingr Mechanism for Em- Eroiderin Machines, of which the following is a speci cation. i

My invention relates to coupling mechanism for couplin the fabric frames of ein broidering machines to their moving mechanism, but I have herein used such designating title onl by reason of the fact that the present em odiment of my invention is shown embodied in an embroiderin organism consisting of the fabric frame o? an embroidering mechanism per se and a jacquard connection coupled together.

In the accompanying drawings in which I have shown one embodiment of my invention, Figure 1 is a side view partly broken away showing one forni of mechanism in which my invention is embodied, Fig. 2 isla section on the line 2-2 of Fig. 1 looking in the direction of the arrow, Fig. 3 is a side cle-` vation of thecompound actuating block With one of its hall` shells cut away for illustrative pur oses, Fig. 4 is a section on the line 4 4 o Fig. 3 with both half shells in lace on the curved middle portion or pin,

i .'5 is a'view similar to Fig. 3 showing the i middle of the pin rectangular and on opposite, sides of said middle portion two sets of Wings or shells, Fig. 6 is a section on the line -f-ef of Fig.' 5, Figs. 7 and 8 are views similar to Figs. 3 and 4 showing another form of block in which the pin is entirely surrounded by a sleeve with plain facets.

In U. S. Letters Patent No. 528632,dated Nov. 6, 1894, I have shown, (see particularly Figs. 4,15, 16, 17 and 18 andlines 119 page 2 to line 1,1 page 3 of said patent) a jacquard mechanism and an embroidering mechanism coupled by a in and roller (bowl) device b. I have oun however, that this arrangement is not the moet ideal device for thepur pose by reason of wear and other causes. It also occurs'V that, the fabric frame beingof considerable length (thirty feet)` the tension of the fabric stretched on the frame or other stress or condition..,will cause the frame to,

ing the Coupling to bind unless it be made flexible in the direction of the strain.

My present invention is designed pri marily to ohviate this and other difliculties should they occur. y

It will be observed that some of the parts in the drawings of the patent referred to are lettered similarly to the corresponding parts in this application.

In the drawing of the patent and in thc `drawings of this application A indicates the fabric frame of an exnbroidering mechanism having in thepresent instance a depending arm a rovided With/a pin c, which enters and is astened in guide or actuating blocks placed at opposite ends of the pin c, one of which works in a slot in the guide B and the other of which blocks works in a slot in the guide C.

In the drawings of this application the Y uides B, (l, cross each other, the guide B being connected to the rack d, and the guide (7 connected to the rack e, see Fig. 2. The rack d, meshes with the pinion f, on the rotatable shaft D, forming part of the jacquard land the rack e, Whichis shown broken away meshes wlth a simllar pinion carrled ona similar shaft of the jacquard. (See pinion g, on shaft D2 Fig. 7, Sheet 7 of the drawing and lines 5 to 10, page 3, of Patent 528632, herein referred to). The block G, may take many forms, three of which I have illustrated in the drawing. In the forms shown herein the idea is embodied of using a pin or stud h aving curved sides (not necessarily circular) surrounded or partly so by a set of saddles, wings or shells or surrounded by a sleeve or set of sleeves` In each case the outer facets or faces of the saddles or sleeves are shown as conformi tothe shape of the grooves in the' cross gpi es B and C. The in c, enters a hole in t e bod of the block and is held firmly therein. or the purpose of this specificatlon and that alone, 1 have shown the block as squared in each case.

Referringfor the resent to Figs. 3 and 4 it willlbe seen that tlhe block G consists of a body, ortion g, apertured at g for the as g in which lor convenience of nomenclature as iliight just as readily be termed shells or wings or any other a propriete desi nation. lt will be observed t .at the space etween the opposite edges of the two saddles g constituting the'set will allow the body g'of the block to swing in the saddles on its axis.

In Figs. 5 and 6 I have shown a similar block Gr.` This block Grl is shown as having at the middle portion of its body g1 a squared portion. g through which the aperture for the pin c passes. Flanking the middle portion g on either side thereof are rounded or cylindrical portions g12 terminat-- ing in collars, flanges or washers '3 g. Seated on these portions glare saddles g'15 ada lcd to swing. In this construction as in t ie construction just described, the faces ol the saddles where they contact with the sides of the Waysin the guides B and C eX- tend beyond the end langes'g13 g1* so that these end flanges do not contact with the guides.

In Figs. 7 and 8 I have shown a block G2 with the curved or cylindrical body portion g2 having a Han e g31 at one end and cap ed at the other end y a Washer g2 held in p ace by a screw y passing through the washer and tapped into the block g3". Intervening between the flange and washer is'a sleeve g24 herein shown as rectan and as Conformin to t e shaft ofthe body 2 of the block 2. They bod g0 of the lock (I2 is apertured at g25 for t e reception of th\e pin c andthe sleeve gzis a ertured at g26 for the passage of the pin c, t e aperture g in the particu ar construction shown being larger than the apertureg25 to allow. for the swing of the pin c. N iet It is thought that the operationl of all the devices showrrand described' will be 'obvious from the description and illustration.

While I liave' herein specifically shown described and to some extent specifically.

claimed certain constructions, I would have it understood that I do not limit 'myselfI to the devices described and shown, as the de vices may be greatly varied without departing from the spirit of my invention.

Having described my invention, what I claim is:-

.1. In a mechanism of the class described, ajg.

fabric frame and means for moving the same,

comprising a guide and moving means for.

the guide and a coupling for coupling the fabric frame and uide, including a coupling block having a ody portion Vadapted to swing plane of the guide and. n gagin the guide and in whiq the b ockis adapted to sv ng.

2. In aamechanism of the c ass described, a fabricframe and a guide adapted to move the saine, means for moving the guide, and a a llin member en-` the bodyof they these curved portions g12 areA lar on the outside.

said guiding on an axis substantially parallel to the' the combination of an embroidering frame,

means for moving thesame and means for coupling the frame and movin means, comprising a bod portion and a in iece engaging with t e moving means an 1n which the body portion may swing.

4. In a mechanism of the class described, the combination of an embroidering frame, means `for movin ,the same comprising a guide and means or movin the guide, and means for coupling the said rame and guide, including ay body portion having circular faces and filling ieces conforming to said uide and in whic the circular faces of said odyare adapted to move.

5. In a mechanism of the class described, the combination of an einbroidering frame, a guide for moving the same, means for moving the uide and a coupling for the'frame and gui e including a body portion, filling means en aging with said guide and in which'saidody portion moves and means on said body portion to.' revent longitudinal dis lacement of said fil ing means from said bo y.

6. In a mechanimof the class described, the combination of an embroidering frame, a guide for moving the same, means for mov- `ing the (guide and a coupling forfthe frame and gui e`includin a body ortion, filling means engagingwit said gui e and in which said body portion moves and flanges on said body portion, within the lateral limits of the filling means, ada ted to prevent the displacement of the ling means.

7. In a mechanism of the class described, the combinatibn of a fabric frame, a plurality 'of substantially parallel guiding members adapted to movesaid frame, and prgvided with guiding grooves on their opposing faces and means members including a plurality be moved by pieces of frame members adapted to said guides and a plurality of .conforming to the grooves in the guiding members and in which the said frame members are adapted to swing, the said filling Aieces being adapted to =travel with the frame members.
